如何在Mac上的ttk/Tkinter笔记本中为框架的背景色匹配? [英] How can I match background colors for a Frame in a Notebook for ttk/Tkinter on a Mac?

问题描述

在Mac上基于Tkinter + ttk的GUI上工作时，我注意到背景颜色和Notebook小部件存在问题.将ttk.Frame添加为ttk.Notebook选项卡时，框架的显示背景与笔记本选项卡的插入"背景不匹配.

如何使ttk.Frame与周围的背景颜色匹配，而无需硬编码对于非Mac用户来说看起来很奇怪的值?

我读了一些关于自定义样式的SO答案，但目前尚不清楚如何在这种情况下查询父窗口小部件的背景颜色.据我所知，它们都是一样的！

>>> ttk.Style().lookup("TFrame", "background")
'systemWindowBody'
>>> ttk.Style().lookup("Notebook", "background")
'systemWindowBody'
>>> ttk.Style().lookup("Notebook.client", "background")
'systemWindowBody'
>>> ttk.Style().lookup("Notebook.tab", "background")
'systemWindowBody'

上述屏幕截图的示例代码:

import Tkinter
import ttk

class GUI(object):
    def __init__(self,root):
        self.root = root
        self.root.title(u"Frame Mismatch Example")
        self.mainframe = ttk.Frame(self.root, padding=(6, 6, 12, 12))
        self.mainframe.grid(sticky='nwse')

        self.notebook = ttk.Notebook(self.mainframe)
        self.tab1 = ttk.Frame(self.notebook)
        ttk.Button(self.tab1, text='Exit', command=self.root.destroy).pack(padx=100, pady=100)
        self.notebook.add(self.tab1, text="Tab 1")
        self.notebook.pack()

def main():
    root = Tkinter.Tk()
    root.columnconfigure(0, weight=1)
    root.rowconfigure(0, weight=1)
    makeGUI = GUI(root)
    root.mainloop()

if __name__ == '__main__':
    main()

重要细节:Python 2.7.8，Tcl/Tk 8.5.15中提供了此信息(Tk.eval('info patchlevel')的报道).

解决方案

我遇到了'systemWindowBody'问题，只是使用sys.platform检查了操作系统，并仅将颜色硬编码为OSX.

如果您有大量的小部件，则可以为OSX使用特定的主题. (这是我发现的一个很好的tkinter主题答案:更改标签标题").

我知道这可能并不理想，但这至少可以确保您不会弄乱其他平台上的外观.

While working on a Tkinter + ttk based GUI on my Mac, I noticed a problem with background colors and the Notebook widget. When adding a ttk.Frame as a ttk.Notebook tab, the displayed background of the frame does not match the 'inset' background for the notebook tab.

How can I make the ttk.Frame match the surrounding background color, without hard-coding a value that will look weird for non-Mac users?

I read a few SO answers suggesting custom styles, but it's unclear how to query for the parent widget's background color in this situation. As far as I can tell, they're all the same!

>>> ttk.Style().lookup("TFrame", "background")
'systemWindowBody'
>>> ttk.Style().lookup("Notebook", "background")
'systemWindowBody'
>>> ttk.Style().lookup("Notebook.client", "background")
'systemWindowBody'
>>> ttk.Style().lookup("Notebook.tab", "background")
'systemWindowBody'

Example code for above screenshot:

import Tkinter
import ttk

class GUI(object):
    def __init__(self,root):
        self.root = root
        self.root.title(u"Frame Mismatch Example")
        self.mainframe = ttk.Frame(self.root, padding=(6, 6, 12, 12))
        self.mainframe.grid(sticky='nwse')

        self.notebook = ttk.Notebook(self.mainframe)
        self.tab1 = ttk.Frame(self.notebook)
        ttk.Button(self.tab1, text='Exit', command=self.root.destroy).pack(padx=100, pady=100)
        self.notebook.add(self.tab1, text="Tab 1")
        self.notebook.pack()

def main():
    root = Tkinter.Tk()
    root.columnconfigure(0, weight=1)
    root.rowconfigure(0, weight=1)
    makeGUI = GUI(root)
    root.mainloop()

if __name__ == '__main__':
    main()

Important details: This is present with Python 2.7.8, Tcl/Tk 8.5.15 (as reported by Tk.eval('info patchlevel')).

解决方案

I ran into the 'systemWindowBody' problem and just checked the OS using sys.platform and hardcoded the color for OSX only.

If you have a large amount of widgets, you could use a specific theme for OSX. (This was a good tkinter theme answer I found: Change color of "tab header" in ttk.Notebook)

I know this may not be ideal, but it will at least make sure you don't mess up the look on other platforms.
